Marlo Assistant Examiner William R. Browne Attorney- William Anthony Drucker ABSTRACT: A catapult attachment for undersea hunting crossbows is equipped with threaded connection points for threaded cords and also with a gapped ring for looped cords so that it is possible to use either type cord or both types together to vary and select the force of the shot according to hunting conditions.

CATAPULT CORD ATTACHMENT DEVICE ON A PROJECTOR The object of the invention is to provide a catapult attachment for undersea hunting-crossbows which allows the simultaneous or separate use of threaded catapult cords and of single-piece catapult cords passing through a gapped ring at an end of the catapult attachment.

' It is characterised particularly by the location in the upper part on either side of the guide tube of two sockets which enable threaded catapult cords to be fitted and by the provision in the lower part of its body and under the guide tube of a gapped ring intended to receive the single-piece catapult cord;

it being specifed that each type of cord can be used separately or simultaneously to produce an exceptionally powerful weapon.

The accompanying drawings, given by way of an example without thereby limiting the scope of the invention, represent one embodiment:

FIGS. 1 and 2 represent the catapult attachment seen in elevation and in plan view;

FIGS. 3 and 4 show the mounting of the catapult cords.

The catapult attachment head (FIGS. 1 and 2) is made up of a body 1 having an upper part and a lower part. On the upper part are tubular screwthread sockets 2, 3 intended to accommodate the rubber cords 4, 5 by conventional means 6, 7.

The lower part of the harpoon guide tube 8 contains a gapped ring 9 which encloses a space 10 provided with a partially closed threading gap 11.

The socket 12 accommodates a known crossbow attachment.

In this way all the advantages and applications of this device are realised.

Because of its diverse nature and unpredictability, undersea hunting generally obliges the hunter to make use of several different weapons.

Under these circumstances one may need an exceptionally powerful weapon for large prey and for shooting at long range and a less powerful one for small fry and for harpooning in holes and crevices.

According to the weapons concerned there are a variety of heads for holding the catapult cords, among them those known as split catapult heads or simply threaded or ringed catapult cords.

With the multi-purpose head one can use the threaded catapult cord or the rapid catapult cord (FIGS. 3 and 4) either separately or together (13, 14 in FIG. 4). To obtain a very powerful effect the number of the Rapid catapult cords may be increased.

The advantages provided by this combination are manifold because they enable the hunter to have at his immediate disposal two appliances in a single weapon without having to decide in advance the type of hunting he will have to limit himself to.

Hunting in holes is made much safer, because the risk of the corals cutting the device is reduced by virtue of the protection of the single-piece" catapult cords by the threaded sleeves acting as fenders. The shape, dimensions and arrangement of the different elements may be varied within equivalent limits, as can the materials of construction used, without thereby chfmging the overall scope of the invention being described.

claim:

1. in the body of a catapult attachment for undersea hunting crossbows, having an upper part and a lower part including guide means for a projectile, the improvement comprising the combination of first means in one of said parts of the body disposed symmetrically adjacent said guide means and on opposite sides thereof for attachment of the threaded ends of a plurality of catapult cords, second means to receive at least one looped catapult cord consisting of a partially closed recess defined by a gapped ring in the other of said parts of the body and socket means located adjacent said recess for receiving crossbow attaching means.
